When installing a grinding or cut-off wheel, did it ever occur to you that the picture should look inward? I recently found out that for many years I have set the circles incorrectly. That is why they often beat and bite.
The next time you change the circle of the grinder, take a closer look. Where the drawing and inscriptions are applied, there is a thin metal ring. It is installed at the factory.
If you turn the disc over, you can verify that this ring is missing.
Learning to clamp discs correctly ...
1. First of all, I recommend that you pay attention to the lower flange (washer), on which the disc rests and against which it is pressed. Its surface is not smooth, but pimpled.
If you set the circle of patterns inward, the metal ring will be opposite the protrusions on the flange. When you grip the disc, the "pimples" will firmly snap into the ring. Thanks to this, the grip will be reliable, the disc will not turn when biting.
2. Secondly, when making circles, manufacturers try to ensure that they lie flat on the base of the grinder.
It cannot be ruled out that bumps appeared on the surface of the disc during its casting. Fortunately, there is a solution to this problem. There is a threaded play on the clamping nut of the grinder. Thanks to this backlash, when you start clamping the circle with the second flange, its possible irregularities will be smoothed out. In this case, the disc will be securely held in the grinder.
3. Thirdly, look at the flap disc. The image on it is on the inside, the ring is also installed there. Suggesting any thoughts?
